This invention consists in improvements in or relating co-knittingmachines and has for its object to provide an improved patterning meansin which one or morev thread-guides is or are employed for supplying astriping thread or threads to the needlesand each guide is capable ofbeing shogged across theline of the needles for the purpose of producingthe requisite pattern;

According to the present invention, a devicefor shogging a thread-guidecomprises in combination two members or two-parts of a single member,which members or parts are so coupied or mounted as to movesimultaneouslyin opposite directions, and a thread-guide supported on orotherwise movable in company at leastone of said members so as to betraversed lengthwise of the needle-bed.

The expression shogging is to be understood as implying that thethread-guide moved lengthwise of the needle bed, that is to say,-alongfrom one needle to another that is remote from it.

In one form of the invention, the shogging device is combined withactuating means to apply, alternately first to one and then to the otherof said members or parts, a thrust always in thesame direction. Thus,the thrustimparted to one member or part will move the other memberorpart in the opposite direction. If, for example,

a thrust imparted to one member or part in one direction causes thethread-guide to be moved, in the same direction as the ground threadmoves,

it follows that a thrust applied to the other memher or part in the samedirection will move the thread-guide backwardly in the contrarydirection.

A modification of the invention comprises the combination of a shoggingdevice for a threadguide, pattern means, and an operative connectionbetween the pattern means and the threadguide whereby the latter isselectively controlled to cause it to bring its thread to the backs .orto the fronts of the needles at will either during the shogging movementor prior to, or subsequently to, the said movement.

Preferably, the thread-guide in its normal po- 1 sition will, during ashogging movement, pass its thread across the fronts of the needles, andthe pattern mechanism, when it is operative on the thread-guide, movesthe latter so as to bring its thread to the backs of the needles.

The foregoing and other features of the inven:

tion will be more clearly understood from the 101- lowing descriptionwhich is that of a preferred .examplelofthe invention given inconjunction with the accompanying drawings, in which 1 Figure 1 is-aplan view of the parts shown in Figure 2 which includes one of severaljacquard devices to be arranged around the patterning head; I

Like reference numerals indicate like parts in all the figures of thedrawings.

In the construction illustrated, there are four depending thread-guides10 which extend lengthwise in the direction of the axis of the cylinderof a stationary cylinder type of machine. Each thread-guide is pivotedbetween, its ends at 11 in one member 12 of the oppositely-movablemembers above referred to, and the other member is shown at 13. Themembers 12 and 13 are movs able lengthwise of the needle bed (whichmeans in circular paths in the machine illustrated, around the machineaxis, since this is a circular machine) on a horizontally-disposedcircular bed 1e supported from a central fixed spindle 15. The latchguard 9 (Fig. 1) can be assumed to be also the revolving thread-guidewhich feeds a thread (the ground thread) to the needles 50,

successively and "from which thread is knitted e. g. in the usualmanner, the ground fabric on which the patterning is done by guides 10.

In the bed 14 there is an arcuate channel for. each member, such as 12and '13, either above or below-said member. In the example illustrated,

the channel is beloweach member and those for the outer members,such as12, are represented by the reference numeral 16, and those for the innermembers, such as 13, are represented by the reference numeral 17. Itwill be seen, particularly from Figure 6, that there are four pairs ofsuch channels intended to accommodate four pairs of members 12 and 13,and each pair of channels 16 and 17 are joined at one end by acommunicating portion 18. A projection from each member 12 and 13extends into its own channel. In Figures 2 and 6 the projection from themember 12 is shown as an arcuate block 118 secured to the member 12 bymeans of screws 19, and the projection from the member 13 comprises twopins 20 and 21 which are secured to the member 13 by means of screws,not shown in detail in the drawings. A row of rolling elements 22, incontact with one another, fills the length of the channel between theprojections from the members 12 and 13 and extends around thecommunicating channel 18. Thus, a thrust applied to either of themembers 12 or 13 in a clockwise direction (viewed in Figure 6) will betransmitted through the rolling elements 22 to the other member to moveit in an anti-clockwise direction.

To a rotary sleeve 23, which surrounds the spindle 15, is secured acollar 24 (see particularly Figures 2 and 9) and from the collar thereprojects a bracket 25 (see Figures 2, 6, 7 and 9) which is in the formof an open frame and supports a spindle 26. On this spindle is rotatablyand slidably mounted a bellcrank 27, 28, one limb 27 of which terminatesin a hook 29 which lies over the bed 14. The other arm 28 extendsupwardly. As will be seen from the drawings, the sliding movement of thebellcrank on the spindle 26 is radial with respect to the axis of thebed 14, and the hook 29, when the bellcrank is at one end of its travel,is in a position to engage the movable members 12, and at the other endof its travel it will engage the movable members 13. The limb 28isengaged by a spring-controlled detent 30 which is pivotally mounted at31 in the frame or bracket 25 and at its other end is normally pulledtowards the arm 28 by a spring 32. The shape of the edge of the detent30 which engages the limb 28 is, 'as shown clearly in Figure 7, such asto assist in a quick snap-over movement of the bellcrank on the spindle26, and to hold the bellcrank at one or the other of its limits ofmovement.

In the operation of the parts so far described, it will be appreciatedthat the bellcrank 27, 28 is revolved around the axis of the fixedspindle 15 and, assuming that the bellcrank is in the position showninFigure 6, and that it is moving in a clockwise direction, it will engagein succession each of the members 13.

It will, therefore, move each of the members 13 in a clockwise directionwhereby the respectively associated member 12 will be moved in ananti-clockwise direction and just as one member 13 reaches the limit ofits travel, limited by the length of its arcuate slot, the hook or claw29 will engage with, and ride up, the sloping cam surface 33 formed on ablock secured to the top of the bed 14. This lifting cam moves the clawout of engagement with the member 13 so that it passes out of contacttherewith and travels round to engage the next member 13 in succession,and so on. It will be understood that there is a block 33 for each pairof members 12 and 13.

As the bell crank 27, 28 returns to its starting position it engageswith an automatic switch-over cam 34. This cam is carried on a spindle35 which depends from a bracket 36 and the latter extends from a bosswhich is clamped to a fixed sleeve 37 that surrounds the rotatablesleeve 23. The switch-over cam is arranged horizontally and pivotedintermediate its ends. The end facing the approaching bellcrank 27, 28is tapered, as clearly shown in Figures 6, 7 and 8. The opposite or tailend is of greater width and the curvature of its opposite edges is suchthat, assuming the arm 28 in travelling round meets one edge of theswitch-over cam, the curvature of the tail end of the latter is suchthat continued movement of the limb 28 past ihe pivot 35 throws theswitch-over cam into its opposite position so that the next time thatthe arm 28 reaches the facing end of the switch-over cam it will engagewith the opposite edge of it. In the foregoing description of theoperation of the bellcrank 27, 28 it was assumed that it was at theinnermost position on the spindle 26. Consequently, the switch-over cam34 will be in the position shown in Figure 7, and as the arm 28 reachesthe switch-over cam it will pass in contact with the outer edge thereof.As the switch-over cam is prevented from turning in an anti-clockwisedirection, by limiting means to be described later, the first effectwill be to push the bellcrank 27, 28 along the spindle 26 to theoutermost position. Further rotation of the bellcrank will cause thelimb 28 to rub against the outer edge of the tail end of the switch-overcam 34 and throw it over from the position shown in Figure 7 (i. e. thechain-line position in Figure 6) to the full-line position shown inFigure 6.

The bellcrank in rotating will now engage in succession with; members12, and again when the limit of movement of each of the members isreached, the hook or claw 29 will be lifted from engagement with themember 12 by means of the associated lifting cam 33. When the limb 28 ofthe bellcrank next r aches the switch-over cam 34, it will engage withthe inner edge thereof whereby the bellcrank will first be moved to itsinner position on the spindle 26 and thereafter the switch-over cam willbe thrown over from the full-line posiiion shown in Figure 6 to thefull-line position shown in Figure 7.

In order to limit the rocking movement of the throw-over cam 34, a crank38 secured to the upper end of the spindle 35 above the bracket 36engages with limiting stops 39 fixed in the bracket 36.

The intention of the construction according to this invention is toprovide a thread-guide, the normal position of which is such that unlessit is disturbed from that position by selecting mechanism it will shogits thread across the fronts of the needles. Nevertheless, the inventionis not so limited to such an arrangement, as will be apparent.

When the thread-guides are shogged in front of the needles the thread inpassing in either direction will be taken into the hooks of the needlesand will be drawn by them. In passing against'the normal direction offeed it is necessary, in order to prevent breakage of the thread, tosupply to each needle substantially that amount of thread required forthe stitch.

For this purpose, beneath the bed 14, and also fixed to the spindle 15,is a tricked dial 49, in the tricks of which are thread-drawing hooks 41(Figures 2 to 5). Each of these thread-drawing hooks 41 stands oppositea space between two adjacent needles, and there will be as many of thehooks as necessary, as will be understood from what follows; usually weprovide a hook for'each of the long inner portions have been omittedfromint'erne'ed-le space throughout the are or arcs swept over by thethread-guideor thread-guides 10. Rotatably mountedon the spindlel5zabove the dial 40 is a cam-carrier in the form of a radial arm 42that has an upwardly-extending jaw 43 embracing a radially-projectingpin 44 secured to the part .45 of the member l2 in which thethread-guide 10 is actually pivoted. Thus; as the pin 44 is oscillatedto-and-fro, the camcarrier 42 will be similarly oscillated. In thecam-carrier isan out-throw-cam 46 and a return cam 47 which engageupwardly-projecting butts 48 formed on the hooks 41'. ThusasSumin'g' thenormal ieed direction is anti-clockwise; with reference to Figures 1, 3and 4, the movement 7 of the thread-guide will be against the normalfeeding direction when'itis' moved in a clockwise Tthread-guide can beeffected by providing adjustable set screws 49 (Figure 2) .which'extendinwardly from the jaws 43 to engage the pin 44 and thereby enable therequisite angular adjustment to be made between the cam-carrier and thethread-guide. yarn after it has been laid around a needle',-one of whichis shown in its normal idle position in.

Figure 2.

On the return-movement of the cam-carrier,- the return-cam will, ofcourse, be clear of the butts 48 of the hooks 41. In order that duringthis movement the hooks shall not operate, the out-throw-cam 46 is, asshown in Figure 5, mounted so that it is vertically movable and isnormally spring-pressed downwardly by a compressionspring 51 containedin a recess in the cam-carrier in which an upwardly-projecting spindlefrom the cam 46 is received' As the cam-oarrier is moved in ananti-clockwise direction, the spring 51 will permit the cam 46 to rideover the tops of the butts. The leading edge of the cam as it engagesthe butts to ride over their tops may be chamfered to facilitate therise of the cam-46 against the spring 51. f

In order to control the action of the threadguides, there is supported,coaxially with the spindle l5 and above the mechanism so far described,a pattern-drum 52 having in it vertical tricks in which sliding bits 53are provided,

These are retained in the drum by-means of the usual spring-rings 54 andat their lower extremities the bits are formed with butts55 which,

by vertical sliding movement-of the bits 53 can be moved into and outfrom the. paths of the upper ends of the thread-guides 19. In Figure 2,a hit 53 is shown on the left-hand side of the drum as having been moveddownwardly so that its butt has engaged an adjustablesetscrew 56 whichconstitutes the operative end of the threadguide 10 and has thrust thethread-guide so' that its thread-guiding portion 57 is in a position toguide the thread across the backs of the needles.

In order to adjust the position of the bits 53 in the drum 52, there isprovided a jacquard-control mechanism comprising a platen 58, endwisemovable radialiy-disposed selectors 59, and a bitwheel 69. In the.machine illustrated, each selector'59 is made up of a long outer portionand a short inner portion joined to the outer portion,

see Fig. 1, and in that figure, for simplicity,- most" The hooks 41engage over thethe drawing. The bit-wheel 60 rotates about an axis thatis "radial with respect to theneedlecylinder and is also revolvedbodily, around that axis. In this wheel sliding bits or intermediateselectors fil-areprovided, and as the wheel rotates on its axis, andaround the axis of the cylinder,

these bits arebrought successively into contact with the .end of thoseselectors 59 that. have been,

moved forwardly by the selective action of the platen and a perforatedsheet "or thelike which passes over the platen in a manner well knownin-jacquard apparatus of this type. The bits 61 when they engage withthe end of the selector 59 are moved radially inward with respect to the1 axis of thespindle l5 and present surfaces which,

as they passover the bits 53 in the drum .52

.will depressthe latter so that the abutments 55 of those bits 53 thusselected are moved intoa position to engage the thread-guides 10.

The bit-wheel is carried in a bracket 62'extending from the sleeve. 63that revolves on the fixed-sleeve 37, and a bevel" wheel 64 on thespindle of the bit-wheel Gilmeshes with-a fixed bevel wheel 65, alsosecured to the fixed sleeve 37l The main drive for the machine isconnected to a vertical shaft 66 which, by means of bevel gearing 67,68drives a radially-disposed shaft 69 above the patterning head. The shaft69 has two bevelled pinions '70 and '7l,'of which the pinion 70 engagesacorrespondinglybevelled pinion '72 fast on the upper end of the sleeve63, and the other pinion'll meshes with the bevelled pinion A'smechanism of this typeris well known, no

further description is thought to-be necessary herein, particularly asthe details of the mechanism constitute no part of the presentinvention.

In the foregoing description, the mechanism.

is described as havinglfou'r thread-guides, but the invention is notlimited to this number as any. other preferred number may be employedand the arc swept out by each thread-guide may be:

reduced or'increased as the number of threadguides is increased orreducedrespectively. Generally, the number of thread-guides will be considerably less than the number of needles because owing to the-shoggingmovement each thread-guide may serve to pass the thread to quite anumber of needles in its own sector or division of the needle-bed- Thepattern proof the thread-guide and partly by theselection duced isdetermined partly by the angular throw imposed on the positionof thethread-guides by means of the jacquard device, bit-wheehandbits 61 and5s.

- There maybe only one jacquard-selecting de vice for the entiremachine. as described in connection with the example illustrated in theac-. companying drawings,'in which case the lay-out for the patternwillbe: repeated at eachthreadguide. The bit-wheel in these circumstanceswill have its bits selected as it travels over the jacquard-selectors 59andno further selection of the bits in the bit-wheel. will take placeuntil it again reaches the jacquard device.= The 'invention is notlimited to the use of one such device Bill I of the needle-bed, a membermovable over said however, as will be apparent to those'skilled in thesematters;

It will be understood that after the bit-wheel has completed arevolution around the axis of the spindle in the example described, (or

rather, after it has passed from the influence of one pattern mechanismand just before it is influenced again by a pattern mechanism) it isnecessary to reset the bits 53 and 61. In order to reset the bits 61, aring 77 loosely encircles the spindle of bit-wheel 60. opposite the endsof the bits 61 and is pivotally mounted at 1'7! in the ends of aU-shapedyoke .78 which'can swing about a pivot-pin '79 which is carriedby bracket From the bottom of the ring '77 there is a projecting pin 80which lies in the path of a camrise 81 formed on ring cam 82 secured tothe under side of the gear ring 65. As'the rise 81 reaches the pin 80 itpushes the ring 77 radially outwards against the ends of the bits 61 andrestores them to the position ready for re-selection by the selectors59.

The bits 53 have overhanging projections at their upper ends which, atthe'required time,'will be engaged by a revolving cam 83 that dependsfrom an arm 84 integral with, or otherwise connected to, and carriedround, with thebracket 62.

Another bracket 85, also carried round with bracket 62, carries aselector return cam 86, which serves to return the selector levers 59after the passage of wheel 60, ready for re-selection.

In' the example described above, it is clear that the thread-guides arenot movable to a sufiicient extent to lay their threads into the hooksof all the needles. That is to say, of the four thread-guides of themachine illustrated, each serves to lay its thread into less than aquarter of the needles in the needle-bed. However, it is obvious ofcourse that each arcuate track may extend for a greater or a lesserangular distance,

and it is not essential to the invention that the arcuate tracks bearranged on the same single level, or that the radii of curvature of theinner tracks be less than that of the radii of the outer tracks as inthe machine shown in the drawings. Furthermore, although the inventionhas been described in its application to a circular knitting machinehaving a stationary needle-cylinder, it will be readily understood by -ithose'skilled in the art, that it. is not limited to the stationarycylinder type of machine, or indeed to circular machines. In general ourinvention is not limited to the details of construction and operationdescribed above and illustrated in the drawings except as appearshereinafter in the claims. 7
